Micron's earnings report, released after the close of the New York Stock Exchange, exceeded market expectations, boosting investor sentiment.
On June 24 (local time), Micron announced that its revenue for the third quarter of fiscal year 2026 (March to May) reached $41.456 billion (approximately 64 trillion won), more than quadrupling compared to $9.3101 billion in the same period last year.

The adjusted earnings per share (EPS) was $25.11, significantly surpassing the market forecast of $20.78. In after-hours trading, Micron's stock price surged nearly 13%.
Han Ji-young, a researcher at Kiwoom Securities, noted, "Considering Micron's earnings surprise and the announcement of SK Hynix's ADR issuance, we may see a concentration in the semiconductor sector today. However, the recent economic burden caused by high oil prices may reduce the frequency of such concentration compared to before."
